Hi all,
My platform information is as follows:
Minnowboard Max.
I use i2cdetect under Linux to detect multiple I2c buses, such as:
I2c-0 Synopsys DesignWare I2C adapter
I2c-10 SMBus I801 adapter at 2000
I can scan the I2c-10 SMbus slave address 0x50 from the SpdRead code in the
UEFI shell to hav
Hi all,
I use the \MdeModulePkg\Bus\I2c\I2cDxe driver and load the driver with the
following command:
load I2cDxe.efi
As a result, both I2cHostDriverSupported and I2cBusDriverSupported get the
returned value Unsupported. The code is as follows:
I2cHostDriverSupported (

Hi all,
I set following command to load i2cdxe.efi:
load I2cDxe.efi.
Then, I set ‘drivers’ in UEFI shell, and the number of devices connected to
this driver is 0.
After I loaded I2cDXe.efi, it showed the messages that I2cBusDriverSupported
and I2cHostDriverSupported returned the values EFI_U
There is has an example of I2cDxe driver in edk2, the path is
\MdeModulePkg\Bus\I2c\I2cDxe.
However, I can't find an I2C example related to the app.
I use the following function, try to get the I2C handle:
EFI_STATUS LocateI2CIO(void)
{
EFI_STATUS Status;
EFI_HANDLE* I2CIOHandleBuffer = NULL;

Hi Michael,
Thanks for your reply.
A few more questions please:
1. In general, not in the Minnowboard environment, but in the Microsoft Windows
environment, are EmbeddedDrivers usually specified?
2. Should the ‘EmbeddedDrivers’ parameter be assigned to ‘FmpDxe.efi’? or
assigned to ‘SystemFirmwar
Hi,
I would like to handle ‘DriverBinding protocol’ model in ‘RegisterFmpInstaller’
to get control of USBIO. Since there is no corresponding example for EDK2, this
part is not easy to implement. Can you provide an example of how
RegisterFmpInstaller handles the DriverBinding protocol, so as to

I can generate Red1.cap capsule file from GenerateCapsule.py of edk2, and
execute CapsuleApp Red1.cap on Minnowboard to complete the process of capsule

Thank you for your response!
Since I don't have SF-100, is there any other way to flash the FW image for
Galileo Gen2 board?
Thanks!
